preparation example Construction

[0021] The preparation method of this high-performance water-soluble acrylic resin is as follows:

[0022] Step 1. Configure the mixed solution

[0023] Hydroxyethyl methacrylate, hydroxyethyl acrylate, methyl methacrylate, isooctyl methacrylate, n-butyl acrylate, ethyl acrylate, acrylic acid, glycidyl tert-carbonate, hexafluorobutyl methacrylate And the initiators accounting for 60%-70% of the total amount of initiators are mixed to form a mixed solution.

[0024] Step 2. Water-soluble acrylic resin molding

[0025] In the reaction vessel, use isopropanol and deionized water accounting for 5-15% of the total amount of deionized water as the base material to raise the temperature to 85-90 °C, and add the mixed solution prepared in step 1 to the reaction vessel dropwise, and the dropping time is 150-200min, then the reaction vessel is kept warm for 150-280min, then the remaining initiator in step 1 is dissolved in isopropanol, and it is added in the reaction vessel, then the ...

Abstract

The invention relates to high-performance water-soluble acrylic resin, which is characterized in that the high-performance water-soluble acrylic resin is prepared by using the following raw materials in parts by weight: 2-5 parts of 2-hydroxyethyl methacrylate, 1-3 parts of hydroxyethylacrylate, 5-8 parts of methyl methacrylate, 3-4 parts of 2-ethylhexyl methacrylate, 6-9 parts of n-butyl acrylate, 3-6 parts of ethyl acrylate, 1-2 parts of acrylic acid, 2-5 parts of tertiary carboxylic glycidyl ester, 1-3 parts of hexafluorobutyl methacrylate, 0.08-0.4 part of initiator, 1-2 parts of neutralizer, 0.01-0.02 part of defoaming agent, 8-15 parts of isopropanol and 10-50 parts of deionized water. By adding two modifiers, i.e. the tertiary carboxylic glycidyl ester and the hexafluorobutyl methacrylate in raw materials for conventional water-soluble acrylic resin, the prepared water-soluble acrylic resin has high alkali resistance and high boiling water resistance, the gloss of products coated with the water-soluble acrylic resin is good and the needs of people are met.

Description

technical field [0001] The invention relates to a high-performance water-soluble acrylic resin and a preparation method thereof, belonging to the field of coatings. Background technique [0002] Compared with traditional solvent-based coatings, water-soluble coatings have the advantages of low price, safe use, saving resources and energy, reducing environmental pollution and public hazards, etc., so it has become the main direction of the current development of the coatings industry. Water-soluble acrylic resin coatings have many advantages such as good leveling, high gloss, good film formation, and good film compactness, which can significantly improve the safety and reliability during construction and curing, and retain the mechanical properties of solvent-based acrylic resin coatings. , protective performance and decorative performance, etc., has become the fastest-growing and most diverse non-polluting coating among water-soluble coatings. [0003] However, the various ...
